2 Claims. (Cl. 292-60) This invention relates generally to metal window frame constructions and, more particularly, to new and useful improvements in a fastener for slidable and removable window sashes, screens, doors and the like.

In metal window constructions, slidable window sashes and screens are commonly provided, but difiiculty has been experienced in holding the frames of the window sash and screen in position.

A principal object of the present invention is the provision of improved spring-pressed means for retaining the sash or screen in position in the window frame construction which will not become displaced accidentally or work loose.

Another object of the invention is to provide an improved fastener for retaining a slidable window sash or screen in position which is automatically adjustable to accommodate itself to abutting surfaces which are not of the same level or which are uneven and irregular.

Another object of the invention is to provide a fastener for retaining a sash or screen in position which is positive in action, highly elficient in use and ornamental in appearance.

It is a further object of the present invention to construct a fastener of the character described which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. l is an elevational view of the interior of a metal window construction with a screen in position and embodying the present invention.

Fig. 2 is a fragmentary vertical sectional view taken on the plane of the line 2-2 of Fig. 1, on an enlarged scale.

Fig. 3 is an enlarged horizontal sectional view taken on the plane of the line 33 of Fig. 1.

Fig. 4 is an enlarged fragmentary sectional view taken through the window frame and showing the fastener in inoperative position.

Fig. 5 is an enlarged top plan view of the fastener.

Fig. 6 is an enlarged side elevation view of the spring.

Referring in detail to the drawings, in Fig. 1 a metal window construction is shown comprising a window frame 10, with a window sash 11 in lower position and a screen 12 in upper position. The sash 11 is provided with an aluminum frame 13 and a glass pane 14. The screen 12 is provided with an aluminum frame 15. The frames 13 and 15 are of the same construction and each is formed with a channel-shaped body into which the ends of the glass pane 14 and the screen 12 are inserted and secured therein by any suitable means, such as a gasket 16.

The window frame 10 is formed of aluminum and includes a hollow box type body with inner and outer walls 17 and 18, respectively, and side walls 19 and 20. A rib 21 projects from the center of side wall 19. When the frame is in position in its opening in the wall 22 of the building, the rib 21 projects inwardly of the frame along its top and sides.

The lower sash 11 and screen 12 are removably mounted in the frame 10 with their side edges abutting against the central rib 21 at both sides of the frame.

An essential feature of the present invention is improved fastening or latching mechanism for retaining the sash 11 and screen 12 in position in the window frame. A number of the latching devices are mounted on the window frame 10 at spaced points therealong, and each latching device, as shown in Fig. 3, includes a latching member having an elongated metal body 23 shaped like an arrow in plan view to provide a neat and attractive appearance. The body 23 has an integrally formed stem 24 depending from the center thereof and extending through an opening 25 in the outer wall 18 of the window frame and into the interior of the frame. The openings 25 are positioned adjacent the inner edge of the window frame. A coiled compression spring 26 encircles the stem 24. The spring is wound clockwise and one full coil 27 at one end of the spring is embedded and secured in a circular peripheral groove 28 formed in the stem adjacent its free end. At the other end of the spring, a full coil 29 impinges against the inner surface of the outer wall 18 of the window frame, pressing the body 23 and stem 24 inwardly of the window frame. The body 23 of the latch is recessed or undercut at one side of the stem 24 as indicated at 30 to form a downwardly extending nose portion 31 on the triangular shaped pointed head 32 of the body 23. The body is also recessed or undercut at the other side of the stern as indicated at 33 to provide a downwardly extending rear edge portion 34 on the tail 35 of the body. The body 23 is comparatively narrow in width and of proper height to form a good finger piece or hand hold for turning the same.

The latching device with its coil spring 26 anchored in the groove on the stem 24 in longitudinally expanded condition is installed by inserting the groove end of the stem through the opening 25 until the lowermost convolution of the spring engages the edge of the opening. By turning the stem in the manner of a screw, the convolutions of the spring and the edge of the opening will coact similar to screw threads in moving the stem and spring inwardly into the interior of the hollow window frame 10, the opening 25 being sufliciently large to receive the stem and spring in such extended condition and permit such movement. When the spring has been moved completely into the interior of the frame and pressure is removed, the spring will automatically contract longitudinally to the condition of Fig. 4.

In inoperative position, as shown in Fig. 4, the latching device is disposed vertically as viewed in Fig. 1. When in this inoperative position, the nose portion 31 of the body 23 and the downwardly extending rear edge portion 34 thereof rest on and engage the outer surface of the outer wall 18 of the window frame 10, and thus resist the force of the coil spring 26 to pull the body 23 and stem 24 inwardly.

It will be noted from Fig. 3 that the outer surface of the body of the frame 15 of the screen 12 is not quite level or flush with the outer surface of the abutting window frame 10 but is disposed slightly inwardly thereof. In use, to fasten the screen frame 15, for example, to the window frame 10, the body 23 of the latching device is manually turned by the fingers of the operator, preferably in a direction so that the nose portion 31 of the body 23 will slide over the outer surface of screen, thereby permitting the nose portion 31 of the positionf' This'pnlling force of the spring" tends to cause the latchingf'devi'ce *to tilt slightlyf toward the' screen "frame 15 as seen inFi'g. 3'; thereby'increasing the grippingjforce of the latching device.
